Fig. 3

The representative images of the epidural fibrosis issues in each group. Laminectomy sites treated with 100 mg/ml suramin (c) and saline (control, d) show that dense epidural fibrosis (asterisk) firmly adhering to the dura mater (arrow). Moderate epidural fibrosis (asterisk) slightly adhering to the dura mater were found in 200 mg/ml suramin group (b). Thin epidural fibrosis (asterisk) with little adherence to the dura mater were found in 300 mg/ml suramin group (a). The spinal cord was represented by “S” and laminectomy defect was represented by “L”. The magnification was ×40
